B) Install and configure a DVD rewrite drive supplied.
Step 1)
Before you start: Ground yourself. Lightly touch your PC's metal chassis to discharge any current from your body. Then unplug the power cable slowly.
Turn off the computer and open the case. Locate an available PCI slot for the MPEG-to decoder card (if your kit includes one). If you're installing a SCSI drive and you don't yet have a SCSI controller in the system, you'll need a second slot for the SCSI card.
PCI : Stands for Peripheral Component Interconnect, a local bus standard developed
by Intel Corporation.
MPEG : Moving Picture Experts Group develops standards for digital video and
audio compression.
SCSIS : Stands for small Computer System Interface, an interface that serves as an
expansion bus that can be used to connect hard disk drives, tape drives, and
other hardware components.
To install any hardware the computer or the Base Unit has to be unplug the
power and the cable, for example the picture showing below.
Step 3)
Locate an available 5.25-inch drive bay that opens into the front of the case, and Remove the bay cover if necessary.
Step 4)
Configure the jumpers on your DVD drive. For an IDE drive, set the jumpers for either master, slave, or sole drive, depending on what else is on the channel. For a SCSI drive, set the jumpers to the correct ID or termination setting
Step 5)
Secure the drive and make sure is properly adjusted.
Step 6)
Attach the cables. Connect the DVD drive to the IDE or SCSI bus and to the power supply. Also connect the DVD drive to your sound card - or connect the decoder card (if included) to the DVD drive and sound card. (If you already have a CD-ROM drive, you can use a micro stereo patch cord to connect the external headphone jack on the DVD drive to your sound card's line-in jack).

The range of utility software
C) As additional information, you will describe the range of utility software currently available. You will include this in tabular form on your blog, containing utility type and detailed descriptions of the use and purpose of the utility.

Explain the effect of computer system and what benefits they bring to the system.
B) Explain the effect of these activities on the performance of the computer system; indicate why they are undertaken and what benefits they bring to the system. This will be added to your blog.

To controls traffic by monitoring the various network ports.
Controlling the various network ports the Windows network USB port
traffic monitoring software is advanced and professional security tool that
provides security from unauthorized access of USB mass storage
removable device usage and the security level in most economical and
efficient way.
Virus Scanner - is computer software used to identify and to remove computer viruses, as well as many other types of harmful computer software.
